Quick changing rear module body vehicle

ABSTRACT

Interchangeable Rear Modular Body Vehicle. This invention would have a driving cab containing everything needed to drive a vehicle, an engine, at least four wheels and a gas tank. The rear of the driving cab behind the driver and passenger doors would be open to the back allowing many different rear body configurations to be attached to the driving cab. This invention with the frame and rear body designs would allow for fast and easy attachment and removal of rear modular bodies. This includes four sliding lock jacks which will be attached to the Rear Module Bodies that will allow these bodies to be removed and or attached to the frame. Jacks will manually deploy from compartments in the rear module bodies by pulling out and disconnecting the rear module body from frame then rotating 90 degrees allowing jacks to lift body off of frame. Jacks will be electrically powered with a control switch located in one of the compartments. Once the rear body module and the frame are separated the electrical power will need to be disconnected using a quick disconnect feature. Allowing the driving cab to be driven to another rear module body. To reattach another rear module body, position vehicle under rear module body aligning frame with the frame channels. Connect electric power and retract jacks which will lower body onto frame. Once jacks are fully retracted, rear module body will need to be locked to the the driving cab by manually rotating jacks 90 degrees and by pushing jacks back into stored position which also locks rear module body to frame.

DETAILED DESCRIPTION

The details of my invention starting at FIG. 1 shows the driving cab with a specialized frame consisting of two rectangular tubular frame rails extending rearward from the cab FIG. 1C. These rails would have an upward slope FIG. 1B starting in front of the rear axle and leveling above the axle to the rear of the frame FIG. 1C. The rear of the driving cab would be open to allow the rear module bodies, which are also open to the front, allowing both body sections to be joined FIG. 2A. All rear module bodies will have two frame channels located on the bottom of the body FIG. 7F and FIG. 8F. These channels will be U-shaped FIG. 9G, conturing precisely around the frames FIG. 1C leaving only the bottom side open FIG. 9H. This open frame channel design will allow for the lifting of the rear module bodies off of the driving cab frame. Each frame rail FIG. 1C on the driving cab will have four mounting holes FIG. 1D, two on the inside and two on the outside, corresponding with each other. These holes would be located on the frame behind the driving cab and behind the rear axle.

The rear module bodies will be fitted with four sliding lock jacks FIG. 5L. The four sliding lock jacks consist of locking tubes FIG. 10M and FIG. 11M. These tubes are shown in a locked position FIG. 11J in which the tube goes completely thru the driving cab frame and the rear module body frame channel. The unlocked position FIG. 10K shows the tube completely disengaged from the frame on the driving cab. These tubes are attached to the jacks FIG. 10N. The tube on the jack system will serve four purposes. First is the locking of the body to the frame FIG. 6J which is showing the tube thru both the frame channel on the module body and the frame on the driving cab. FIG. 6G is the frame channel in the module body and FIG. 6C is the frame on the driving cab. Second, is to allow a 90 degree rotation of the jack from the horizontally stowed position FIG. 2S, to the vertically deployed position FIG. 3R which would allow the jacks to lift the rear module bodies from the driving cabs frame. Third, is to create a clearance FIG. 10O from the rear wheels of the driving cab. The fourth purpose would allow supporting of weight of the rear module body when detached from the frame of the driving cab. This would allow for free standing of the rear module body FIG. 4. After the rear module body is detached from the driving cab, the driving cab can be driven away to another free standing rear module body.

When attaching the rear module bodies to the driving cay frame, the frame channels on the module body FIG. 6G and the frame on the driving cab FIG. 6C will be aligned. Then when lowering bodies onto the frame, the slope of the frame FIG. 1B in front of the rear axle will create a forward push towards the driving cab, allowing for a tight fit between the rear module body and the driving cab FIG. 2A. The rear of the driving cab will have a slight angle going forward from bottom to top FIG. 1A this angle will match the angle on the front of the rear module body FIG. 2E. This would ease friction between the weather-stripping while engaging and disengaging the bodies from one another.

The rear module bodies will have four compartments which will house the sliding lock jacks FIG. 3Q. The sliding lock jacks will have body panels attached on the outside FIG. 3R. Which when closed FIG. 2S will conceal the compartments and sliding lock jacks. On the insides of the compartments there will be manual lever mechanisms FIG. 6P that locks and unlocks the tubes on the sliding lock jacks.

SUMMARY

This invention consists of a driving cab with a rear frame system that would allow fast and easy removal of rear body modules. There would be no tools necessary for removal or attachment of bodies. It is simple enough for a person with little mechanical knowledge to use the sliding lock jacks. He/She can transform the vehicle from one type to another, ie: regular cab pickup truck, extended cab pickup, crew cab pickup, flat bed truck, suv, van, crossover, camper, ect. in just minutes. Please do not publish. 

1. Rear Module Body with frame channels which contour to top and sides of frame of vehicle.
 2. Frame and cab design which allows for rear body to slide forward, giving rear module body and vehicles cab a tight fit.
 3. Four frame mounting holes on each rail which correspond with sliding lock jacks.
 4. The sliding lock jack system allows for fastening rear module body and frame together and also allows for the lifting of rear module body for removal of vehicle.
